C/2009 R1 (McNaught), one of more than fifty comets known as Comet McNaught,[4] is a non-periodic comet discovered by British-Australian astronomer Robert H. McNaught on September 9, 2009, using the Uppsala Southern Schmidt Telescope at Siding Spring Observatory in New South Wales, Australia.[5] The discovery was confirmed the same day at the Optical Ground Station telescope at Tenerife.[5] After the discovery, earlier images of the comet were found from July 20, August 1, and August 18, 2009.[5] It is believed that C/2009 R1 has left the Solar System permanently.[3]
